INCANDESCENT GAS-BURNER SPECIFICATION forming part of Letters Patent No. 662,323, dated November 20, 1900.

, Application tiled April 23, 1900. Serial No. 13,961. (No model.)

To @ZZ whom it may concern:

Beit known that I, CLARENCE W. TAYLOR, a citizen of the United States, residing Vat Sioux City, in the county of Woodbury and State of IoWa,-have invented new and useful Improvements in Incandescent Gas-Burners, of which the following is a'speciication.`

This invention relates to incandescent gasand arrangement of parts hereinafter de-` scribed, and particularly pointed out in the claims following the description, reference be ing had to the accompanying drawings, forming a part of this specification.

Figure l is a vertical central sectional View of myimproved incandescent gas-burner, and Fig. 2 is a horizontal section taken on the line 2 2 of Fig. l. I

Referring to the drawings, the numeral l indicates a gas pipe ortubeinternally threaded at its lower end for attachment to an ordinary gas-fixture and open at its opposite upper end. Supported on the lower end of the tube l is a casing 2, preferably flared outwardly near its upper end and having fitted in said flared portion a horizontal diaphragm or partition et, said casing constituting an air-chamber. In the cylindrical portion 2 of the casing are formed perforations or apertures 5, and arranged to be freely moved up and down thereon is a flat ring 6. By adjusting the ring up or down over the apertures 5 the latter may be covered or uncovered to a greater or less extent to regulate the admission of air to the air-chamber in a Well-known manner. p The casing is continued up above the diaphragm 4L to form an inclosing-wall, as at 6, and is provided at its upper end with a horizontal diaphragm or partition 7, from the center of which rises a vertical tubular casing or hood 8, closed at its .small perforations lO, through which the mixed air and gas escapes, as will more fully hereinafter be explained.

Formed centrally on the upper end of the hood or cap S is a stud ll, on the upper reduced end of which is fitted a collar l2, provided with a plurality of radial arms 13, carrying at their outer ends a ring la. An incandescent mantle l5 is attached at its upper end to the ring 14. and at its lower end falls about the Wall 6 of the air and gas mixing chamber, a space being thus inclosed by the mantle and between the latter and the hood or cap 8, into which the mixed air and gas escapes.

The usual wirelgauze disk 16 may be fitted in the lower end of the tube l for a purpose well understood.

The operation of my improved incandescent gasburner is as follows: The burner is to be attached to an 4ordinary gas-iixture in place of the usual tip-burner. Let it be assumed that the burner is in operation, at which time the mantle l5 will be in a high state of incaudescence, as is well known. The gas passes up the central tube l and out the upper end of the latter, thence down the cen tral space between said tube and the hood or cap 8 and into the air and gas mixing chambei". Atmospheric air enters the air-chamber through the apertures 5 and from the airchamber escapes through the apertures 9 into the air and gas mixing chamber, and from the latter chamber the mixed air and gas passes into the space inclosed by the mantle, whereitis ignited and consumed. The hood or cap 8 being inclosed in the highly-incan descent mantle is heated and kept heated to a high temperature, and the hood or cap thus forms a heater which operates to heat the gas before it enters the air and gas mixing chamber, and thereby causes the gas when it en- IOO ters said chamber to readily commingle and mix with the air, whereby a highly-efficient union of the two is effected in a manner to promote the most perfect combustion. OW- ing to the described location of the perforations 10, the gaseous mixture is delivered in close proximity to the inner side of the incandescent mantle in a most advantageous manner for being ignited and consumed. The

admission of air to the air-chamber is controlled by adjusting the ring 6 in the manner before described, While the admission of gas to the burner may be regulated by the usual cock in the gas-ixture or in the following manner: It Will be noted that the casing is threaded at its lower end, as at 17, and is screwed over a correspondingly-threaded portion of the gas-'tube l. Hence,if the casing be screwed up or down on said tube, the upper end of the latter will be adj usted toward or from the upper closed end of the hood 8, thereby regulating the amount of gas passing to the mixing-chamber and incidentally limiting or extending the capacity of the said heatingchamber.

By means of the arrangement above described the gas is not only heated preparatory to its being brought into contact with the air to enable the air and gas to readily unite, but the resulting gaseous mixture that is brought into contact with the mantle is also heated, whereby there is no tendency of the air and gas to cool the mantle, as is the case in the burners now in ordinary use.

Having described my invention, what I claim is- 1. In an incandescent gas-burner, the combination with the central gas-tube, of a casing supported on the lower end of said tube and closed at its upper end by an air and gas mixing chamber, air-inlets in said casing, air-passages in the bottom of the said chamber foradmitting air thereto from the casing, a hood surrounding the upper end of the gastube and communicating at its lower end with the air and gas mixing chamber, a mantle suspended over the said chamber and inclosing the hood,and means for feeding mixed air and gas from the mixing-chamber to the interior of the mantle, substantially as described.

2. In an incandescent gas-burner, the combination with the central gas-tube, of a .casing supported on the lower end of said tube and closed at its upper end by an air and gas mixing chamber, air-inlets in said casing, airpassages in the bottom of said chamber for admitting air thereto from the casing, a hood 4surrounding the upper end of the gas-tube and communicating at its lower end with the air and gas mixing chamber, a mantle suspended over the mixing-chamber and inclosing the hood, and an annular series of perforations formed in the top of the mixing-chamber near the outer edge of the latter, substantially as described.

3. In an incandescent gas-burner, the combination with the central gas-tube, of a casing supported on the lower end of said tube and closed at its upper end by au air and gas mixing chamber, air-inlets in said casing, an annular band movably arranged on said casing over the air -inlets, airpassages in the bottom of the mixing-chamber for admitting air thereto from the casing, an annular series of perforations in the top of the mixing-chamber near the outer edge of the latter, atubular hood surrounding the upper end of the central gas-tube, said hood being closed at'its upper end and communicating-at its lower end with the mixing-chamber, and a mantle suspended over said mixingchamber and surrounding the hood, substantially as de-` scribed.

4. In an incandescent gas-burner, the combination with the central gas-tube, of a casing itted on the lower end of the tub'e and provided near its upper end with a perforated diaphragm dividing said casing into a lower air-chamber and an upper air and gas mixing chamber, the air-chamber being provided .ared outwardly at its upper portion and terminating at its upper end in a cylindrical portion, a perforated diaphragm arranged in said cylindrical portion and on the upper end of the flaring portion, said diaphragm dividing the casing into a lower air-chamber and an upper air and gas mixing chamber, the air-chamber being provided with air-inlet openings, an upwardly-projecting hood fitted in the upper end of the air and gas mixing chamber and surrounding the upper end of the gas-tube, a mantle suspended about the air and gas mixing chamber and inclosing the hood, and means for feeding mixed air and gas from the mixing-chamber to the interior of the mantle, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.l
